Lyrics
Introduction
Nowadays, music is a big part of people’s life. Lyrics is considered as the soul of music. There are so many kinds of music, like Rock and Metal, but, as for me, I am not familiar with all kinds of genres. So, in this project, I am trying exploring the lyrics and understanding the underlying things behind the music’s genres.
Exploring the relationship between the lyrics’ length and genres
From the histogram, we notice that the number of words in hip-hop music is commonly more than that in other genres.
Also, in the boxplot, we can see that hip-hop contains the most words and the eletronic has the least.
From the violin-plot, it is shown that, the number of words in the genres, such as country, jazz and rock music, is kind of consistent as time goes by. The Eletronic music has the longest range in the number of words. For next step, I am trying to figure out the relationship between the distribution of number of lyrics and the decades, so I pick the Metal Music as the example.
The number of words in Metal Music’s Distribution
According to the ridges plot, there is evident that the length of lyrics is increasing and the distribution became more concentrated as the year goes by.

The top 10 popluar words in each genre
As we can see, except for Metal, love is used the most frequently by all the genres, and word “love” is mentioned over 80000 times, which is the highest in all genres. However, in metal music, the terms like “life” and “time”, are mentioned more than the term “love”. I guess this is resulted by the core of metal music, the aggressive attitude about life rather than the joy of the world. We also can conclude this from the word cloud of metal music’s lyrics.
Wordcloud of Metal Music
This wordcloud contains the top 200 frequently used terms in metal music, and we can observe that most of terms express negative feelings like die, pain and lie. Hence, I guess the major emotion of metal music is negative. In order to explore the emotion underlying the metal music, we use the sentiment analysis.
Semtiment analysis on Metal Music
As we can see, the top 5 major feeling of the metal music is negative, positive, fear, sadness and anger, and four of five suggest the darkness of life. Hence, we can infer that the reason why metal music is less often to mention the term “love” is that its major emotion is negative. We also can use the sentiment analysis on all the genres to prove that.

I wanna find out the distribution of metal music as years goes by. As we can see from the pie chart, the first metal music was created in Sweden. And during 1985 to 1995, most of metal artist were still from Sweden, with a few of them came from the United States. During 1995 to 2005, the metal music was spread to other European coutries, such as Finland and England. After 2005, the metal music is spread around Europe, North America.
